Abstract: 215,275. British Thomson-Houston Co., Ltd., (General Electric Co.). Nov. 20, 1923. Systems controlling travel for a fixed distance. -In controlling electric motors for operating valves and the like, the speed and torque of the motor are. automatically reduced when the operation is nearly completed, and a time limit or overload controlled switch is relied upon to open the circuit of the motor after it has been brought to rest. Fig. 1 shows the general arrangement of the invention in the case of a direct-current shunt wound motor 11 operating a valve 10, and started by push-buttons 20, 21 in connection with pairs of reveirsing contactors 12 - - 15. Towards the end of the full travel, one of two limitswitches 16, 17 in connection with a solenoid switch 18 puts resistances 27, 28 respectively in series and in shunt with the motor armature. The solenoid also sets in action a time-limit. relay 19 which is calibrated to open the circuit after sufficient time has alapsed to bring the motor to rest by the valve jamming. In a modification, the time-limit relay is replaced by a relay responsive to rise of current due to the stalling of the motor. In other modifications, alternating current motors are used, and the reduction of speed and torque is obtained either by resistances in the stator circuit, or by altering the number of poles.
